Human Organs make up the six key body systems. These are the skeletal system, muscular system, nervous system, digestive system, respiratory system and circulatory system. Lets explain how each of these play a role in sustaining and functioning of the human body.

Skeletal system provides structure to the body and protects internal organs. It is made of bones, skull and skeleton. The muscular system supports the body and allows it to move. Biceps and triceps are examples of muscles found in this system. The nervous system controls thought, sensation, movement and virtually all body functions. The key part in this is played by the brain.

Digestive system breaks down food and absorbs nutrients. It consists of the stomach, small and large intestines and other parts. The respiratory system takes oxygen and releases carbon dioxide through lungs. Finally the circulatory system with heart at its core transports oxygen, nutrients and other substances to cells and carries away waste.

The below diagram displays where each of these organ systems is located in the human body.
